Java Chat System
1
INTRODUCTION PURPOSE OF THE PROJECT
The Project JChat is a Java client/server combination, which can be used to chat over the Internet or local networks. Anyone can run a Java client or server, so you can host lots of guests on your own computer, or you can join in on someone else's session.
The client
can be used as a Java applet, so it's simple to add chat functionality to your web site. The program's premier feature is its whiteboard drawing utility. You can draw freehand, do circles, squares, lines, text, or paste image files to the canvas. This is ideal when users want to "sketch" concepts for one another. Users can interact publicly with everyone else on the server, or they can chat/draw privately using java Chat's "whisper mode". Users can create and manage chat rooms, which can be either "public" or "private". The server will also store and manage answering machine-style messages for users who aren't online, and instant messages can be sent to those who are. Additionally, users who aren't watching their screens can be paged with sound. PROBLEM IN EXISTING SYSTEM Have you ever wanted to talk with other computer users in other parts of the world? Well guess what? You can! The program is called Chat, when you are Chatting, everything you type will instantly be transmitted around the world to other users that might be watching

their terminals at the time. They can then type something and respond to your messages, and vice versa. Chatting is based on a client-server model. Clients are programs that connect to a server; a server is a program that transports data, (messages), from a user client to another. There are clients running on many different systems that allow you to connect to a Chat server. Currently most of the current Chat applications are text based and few are capable of transferring tiny images, but there lacks a Chat system for the technical people who can chat as well as they can represent their ideas in the form of drawing the pictures online. Many vendors distribute even these technologies separately but to obtain these features at one system will be the haunting task. SOLUTION OF THESE PROBLEMS To solve the inconveniences as mentioned above, an “JAVA CHAT” is proposed. The proposed system’s premier feature is its whiteboard drawing utility. You can draw freehand, do circles, squares, lines, text, or paste image files to the canvas. This is ideal when users want to "sketch" concepts for one another. This feature of “JChat” can be a boon for the technical people who want to share their ideas or concepts in the pictorial form. This system includes the facilities of traditional chat servers and clients like providing a window for each Other user, Whisper chat, multiple chat rooms etc. SCOPE OF THE PROJECT The World Wide Web is a network of information, accessible via an easy-to-use interface. The information is often presented in hypertext or multimedia and provided by servers located around the world. The

usability of the Web depends largely on the performance of these servers. This application is a Java client/server combination, which can be used to chat over the Internet or local networks HARDWARE & SOFTWARE SPECIFICATIONS 1. Windows XP or later version operating systems running on Intel hardware. 2. A Pentium 166 MHz or faster processor. 3. At least 32 megabytes of physical RAM is required to run GUI applications. Forty-eight megabytes is recommended for applets running within a browser using the Java Plug-in product. 4. Running with less memory may cause disk swapping, which has a severe effect on performance. Very large programs may require more RAM for adequate performance. 5. Java 1.5 or later
